A 8 km long and 3,35 m in diameter wide water collector tunnel created by using a Robbins Tunnel Boring Machine (TBM) on the island of Eysturoy. It is located close to the bridge between Stremoy and Eysturoy, and goes from Norðskáli to Selatrað.

Minerals were collected in 2012, during the construction period.

Coordinates are for the approximate half way point of the tunnel.
